If the plural form of goose is geese, then it should follow that the plural form of moose is meese. But the English language disagrees. The plural form of moose is the same as the singular form. The crazy language is indeed crazy and mind-boggling at times.
Mitchell Moffit wrote a poem pointing out these absurd contradictions in the English language. Although it's fun to watch, it also makes you sad as you think of the folks trying to learn English and coming across these absurdities.
